Leners Parma No. 93,037, dated July 27, 1869;

IMPROVEMENTl IN 'WATER-WHEELS.'

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Beit known that I, S. H. BARNES, of Lanesborough, in the countyl of Susquehanna, and State of Pennsyl- Vania, have invented a new and useful Improvement in Water-IITheels; and I do. hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, formingtpart of this specification.

This invention relates to improvements in waterwheels, designed to provide'certain improvements in the gates, calculated to facilitate the operation thereof; also the delivering of the water upon the buckets in a manner to have the best effect; also certain improvements in hanging the wheels; all as hereinafter more fully specified.

Figure l represents a top view, partly in plan and partly in horizontal section, and

Figure 2 represents a vertical section, taken onvthe line n: x of fig. 1.

Similar letters of reference indicate corresponding parts.

A represents the buckets of a turbine wheel, of which B isthe top of the case, and (l the curved chutes,for directing the water to the said buckets. i

. E represents the gates, which are of plano-convex form, and supported at top and bottom in journals,

whose axes are coincident with the axes of the convex portion thereof, and so alranged, with reference to the mouths of the chutes, that when turned int-o the position represented in red at F, the passage of the water to the buckets will be stopped.

The upperends. of these gates are provided with gear-wheels G G, geared with a lar'ge wheel, H, by which all the gates are opened and closed simultaneously, and the proper relative positions of the gates maintained.

In gearing these gates with the wheel H, it is important that they be so adjusted, that in `opening' they will turn against the points of the preceding chutes, as represented in g. 1, by which theyguide the water -more directly to the buckets than when opening in the opposite direction. Yet the opposite direction may be available.

This arrangement of the buckets is also advantageo us in cases when it is not required to apply the whole amount of water which the wheel is capable ofl taking,

as they open equally from bottom to top,.and thus deliver the lesser quantity equally inthe buckets. Y

My improvement in suspending the wheel consists in the arrangement 'of a hollow convex block of -wood,

I, on the top ofthe curve, or other support, above the same, and the concave collar K, on the shaft, to bear thereon.

The shaft is supported principally by the collar K, while the bearings, above and, below, are designed as guides to prevent the displacement of the 'shaft laterally.

In order to prevent the wear of the metal collar K, the block of Wood I is inserted in the top of the curb, as before stated.

Having thus describedmy invention,

I vclaim as new, and desire to secure by Letters Patent- 1. The plano-convex gates E, arranged inthe mouths of the chutes, and geared with the wheel H, substantially as specied.

2. The arrangement of the hollow convex bearing I, upon the case, or other support, about the wheel, and the concave bearing K, substantially as specified.
